Hi,
I have a Hatachi AXM89MP3uk sterio that will be 2yrs old on 23rd Dec.
It has just stopped giving any output. No buzz as the speakers are connected or disconnected and the same for the headphone socket.
The CD player is reading the disc, and shows time elapsed etc. so it seems to be playing, the tuner is showing the sterio symbol as if it has a good signal, but no output through the speakers or headphones (both have been tried on other equipment and are working fine) is this a common fault and/or easily repaired?
Thank-you in advance for any time taken over this matter.
Kindest regards,
Sev.

I had this problem and found that it was a capacitor broken on the main circuit board. It was capacitor 639 which is a 20nF ceramic capacitor. I only had a 100nF so switched the faulty one for this, replaced the fuse F2 and it now works fine. If the fuse is blowing It is most likely this capacitor or the one above it, or the diodes next to them. When this capacitor breaks it puts 28Vac across the fuse and blows it. If you can use a soldering iron its not too difficult to fix. Hope this helps.

Hi I don't have a solution but the same thing has happened to me. I opened it up and found that the "fuse 2" had blown. I replaced the fuse but it blew as soon as I plugged the unit back in. If anyone knows why this would happen after 2 years I would love to know.

1, switch the working right speakers cable to left output and problem left to right (from the back of receiver -not from the speakers it self..) to see if problem continues..

2.After switching them ,if it (old left new right one ) still stops left speaker cable may have short ( a tiny cable inner pieces may touching to other side ) at either at the back of receiver output or at the end ,at speaker input .make sure you control it carefully...if the problem persist please contact to me..

I'm thinking you have an open shield ground on the RCA input side. Connecting speaker inputs possibly restores the ground. Try connecting the high level inputs then disconnect the remote end of the cables (floating the grounds).

Then get out an ohmmeter and find that open circuitor or bad solder joint between RCA ground and real ground in the speaker's amplifier. Or.... if speaker ground kills the hum and you want to use RCA Line Level input to the sub, just connect one minus speaker output on your source amp to one minus on the sub's amp.

If you don't have a local service shop, then please post your general location here so we can provide guidance. Typically any TV service shop will either service the unit directly or deal with someone that can service audio equipment. We will be happy to provide a reference once your location is known.

your laptop has an audio output jack that is 1/8 inch sterio .. your sound system likely has RCA input jacks .. you can get a cable from radio shack that has a 1/8 inch (3.5mm) sterio plug on one end and two RCA plugs on the other ..
plug the 1/8 inch jack into your computers audio output (headphone jack) .. the RCA plugs will connect to the AUX (analog) input on your sound system .. select AUX on your sterio system to select the computers input .. now you should have great sound from your computer . the computer likely provides only sterio information so the multi (7) channel feature of your sound system will have to fake it ..

Remove the bridging links from the speaker terminals and run two equal lengths of speaker wire from the amp to the speaker. At the amp - speaker terminal, twist two of the same wires together. ( normally marked with a tracer color) Connect these into your left speaker output - terminal and tighten. Connect the two wires to both the negative terminals on the speaker. Repeat the same for the + side. Make sure wires are not shorting across the terminals.

cd players work without use of volume controls coax cables hook up's and then by setting reciever to proper button so sound can come out
you might have had a power surge that fried your system but lets look at easy stuff first
fuses
lines in properly and connected
test on an old sterio with speaker hook ups and test your speakers by plugging in to old beat box
make sure wires are not scorched
turn on receiver fm see if speakers work change channels to sterio and mono settings if speakers start to work on sterio or mono setting chances are power surge blew out your system
hope this worked

You've got a fried output transistor or one of the small preamp transistors that feed the output on the left channel. Both of these transistors are after the volumn control so it would have no effect on the buzz. Good luck.
